HEATING ELEMENT HAVING A PLANAR, HEAT-GENERATING LAYER

摘要

The invention relates to heating element, comprising a planar, heat-generating layer (100) and two electrical contacts (101; 103) for providing an electric heating current, wherein the electrical contacts (101; 103) are arranged on the heat-generating layer (100) on opposite sides of the layer (100), wherein at least one of the contacts comprises a first contact element (102) and a second contact element (104; 200), wherein the first contact element (102) extends in the heat-generating layer (100) in an undulating manner as viewed in a first plane (112) perpendicular to the extent of the layer (100), wherein the second contact element (104; 200) extends parallel to the extension direction (106) of the first contact element, wherein the first contact element (102) and the second contact element (104; 200) have a plurality of common contact points as viewed in the extension direction (106).
